Abstract
The utility model relates to a high-frequency triggering and hammering switch for seismometers, which is composed of an iron circular ring, a circular sponge sheet, a piezoelectric ceramic sheet, a horn which is made of high pitch paper film and a pressure sheet. When the utility model is used, an electrical signal generated by the high-frequency triggering and hammering switch for seismometers reaches a high frequency signal (the highest frequency reaches 17000Hz) which is used as a trigger signal for instruments. The frequency of the trigger signal is increased, and the firing signal and the trigger signal of the instrument are delayed to be small. When the signals are observed repeatedly, the repetitive error is reduced, and the exploration precision and the detection precision are increased. The utility model not only can be used on the seismometer exploration and detection, but also can be used as the high-frequency triggering hammering switch on other various instruments.
Description
The utility model belongs to a kind of seismograph and triggers the hammering switch, is doing the engineering prospecting, and wave velocity testing, velocity of wave are surveyed into, and pile foundation detects, and uses during hammering focus such as shallow seismic section.
The current engineering investigation that is used for, wave velocity testing, velocity of wave are surveyed into, and pile foundation detects, the seismograph that hammering focus such as shallow seismic section use trigger the hammering switch all with instrument from foreign import, this switch is vibrated the pulse signal that electric impulse signal that the back produced belongs to low frequency.
The purpose of this invention is to provide a kind of seismograph high frequency and trigger the hammering switch, the electric signal that the hammering switch is produced reaches a kind of high-frequency signal and does trigger pip to instrument, and controls the signal frequency of piezoelectric ceramic piece with high pitch paper film.
The present invention realizes like this.End by-level is placed circular sponge sheet in having the irony circle cup of 2 lead fairleads, and makes the two bonding; Horizontal positioned piezoelectric ceramic piece on the sponge sheet, the ceramic plane of piezoelectric ceramic piece outwardly, piezoelectric ceramic piece and sponge sheet bonding, 2 leads are drawn at connector lug place at 2 opposed polarities of piezoelectric ceramic piece, lead passes 2 lead fairleads of irony circle cup, the side bonding of the toy trumpet mouth of the horn body made from high pitch paper film and the piezoelectric ceramic piece that pottery is arranged, horn body typhon mouth and irony circle cup rim of a cup bonding are stamped compressing tablet, compressing tablet and rim of a cup bonding on the rim of a cup, circular sponge sheet, piezoelectric ceramic piece and irony circle cup inwall are gapped, piezoelectric ceramic piece, circular sponge sheet, irony circle cup, the circle central axis of horn body is on the same circle central axis.
Be elaborated below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of embodiment.
Method for making and step:
Embodiment 1, cut-off directly are 3 one of the piezoelectric ceramic pieces of 15-25mm; Diameter 35-45mm, 1 one of the circular sponge sheets of thick 2-4mm; The big mouthful of diameter made from high pitch paper film is 40-50mm, osculum diameter 5-15mm, 4 one of the horn bodies of high 10-20mm; With 2 one in the round cup of the irony of 2 lead fairleads, circle cup diameter 40-50mm, high 15-25mm; Diameter 40-50mm, 5 one of the hard compressing tablets of thick 1-2mm.
2, circular sponge sheet 1 is placed horizontally at centre position, the end in the irony circle cup 2, both is bondd with 502 glue, gapped around the sponge sheet 1 with circle cup inwall.
3, piezoelectric ceramic piece 3 is placed horizontally on the sponge sheet, not with the side of pottery and sponge sheet with 502 glue bonds and the circle central axis of circular sponge sheet and piezoelectric ceramic piece is on the same axis.
4, draw two leads and pass 2 fairleads of irony circle cup from the wiring point of 2 opposed polarities of piezoelectric ceramic piece 3.
5, the side 502 glue bonds of the band pottery of the toy trumpet mouth of the horn body made from high pitch paper film 4 and piezoelectric ceramic piece 3, again the high pitch paper film of typhon mouth and 502 glue bonds of irony circle cup rim of a cup, make toy trumpet mouth and piezoelectric ceramic piece be in the concentric circles position during bonding, and horn body 4 threes' that circular sponge sheet 1, piezoelectric ceramic piece 3, high pitch paper film make overall height is highly equated with irony circle cup 2, the diameter of the irony circle cup that in 1, uses and the typhon mouth equal diameters of horn body.
6, use a hard compressing tablet 5 with irony circle cup rim of a cup equal diameters to cover rim of a cup and both are bondd, promptly become seismograph high frequency triggering hammering switch with 502 glue.
Advantage of the present invention is that the signal of telecommunication that the hammering switch is produced reaches a kind of high-frequency signal (highest frequency reaches 17000Hz) and does triggering signal to instrument, improve the triggering signal frequency, it is little that percussion signal and instrument triggering signal are postponed, repetitive error reduces during repeated measures, improves investigation accuracy and accuracy of detection. Not only can be used in seismic detector prospecting, the detection, and can make high-frequency triggering hammering switch at other multiple instruments and use.
